The international symbol of a lightning bolt inside a triangle is intended to alert the user touninsulated “dangerous voltage” within the device’s enclosure. The international symbol of anexclamation point inside a triangle is intended to alert the user to the presence of importantoperating, maintenance and servicing information in the manual accompanying the device.
To prevent electrical shock, match wide blade of plug to wide slot, fully insert.
To reduce the risk of electrical shock, do not expose this equipment to rain or moisture.
To reduce the risk of electrical shock, ensure the voltage selector switch is selected to theappropriate supply voltage.

Bryston PIUs (Power Isolation Units) combine the best surge
suppression with unique toroidal transformer technologies
from PLITRON to provide the ultimate in AC power
conditioning and protection for sensitive audio and video
equipment applications.
PIUs use ZeroSurge patented series-mode surge removal
filters to absorb dangerous voltage surges and safely dissipate
them without using failure-prone MOVs (metal oxide
varistors). Also, unlike MOV-based protection, voltage surges
are not shunted to ground.
Isolation is combined with proven proprietary technologies
from PLITRON in the over-sized toroidal transformer. NBT
works as a low pass filter using the controlled leakage
inductance and capacitances within the transformer to cancel
common mode and differential mode noise. LoNo technology
has been used for years by high-end audio companies who
demand silent transformers. Imin technology reduces inrush
currents. UST provides additional common mode filtering
using a highly efficient faraday screen.
Low-impedance output with balanced high-power primary
input provides the most unconstrained, yet protected, energy
source available to your equipment.
Description
Please keep the original shipping box and all packingmaterial.
This will ensure the PIU is protected in future transport.
In the unlikely event you have a problem andmust return it for
service youmust use the proper packingmaterial.
Ship the PIU only in the original packingmaterial, as the unit is
not insurable by carriers otherwise.
Shipping Carton & Packing Material
Bryston Power PIUs are extremely efficient devices, however,
they are also very high-power devices, and must be
adequately cooled.
Do not install the PIU directly above heat-generating
equipment.
Maintain at least 15cm behind the PIU for adequate wiring
space.
PIUs have ventilation slots on the base, side panels and the
cover. Maintain at least 2.5cm distance from each of these
surfaces to anything else. Should your installation conditions
be constricted, additional forced air-cooling may be
necessary.
Placement & Ventilation
Bryston BIT power isolation products are warranted to be free
from manufacturing defects for a minimum of five years from
the original date of sale. This includes parts, labour and return
shipping to the first registered owner and all subsequent
registered owners. Warranty coverage is extended to
applicable products registered or having proof-of-purchase
(sales invoice, etc.).
In the event of a defect or malfunction, BIT Power will remedy
the problem by repair or replacement, as we deem necessary,
to restore the product to full performance.
This warranty is considered void if the defect, malfunction or
failure of the product or any component part was caused by
damage (not resulting from a defect or malfunction) or abuse
while in the possession of the customer. Failure to fully comply
with BIT Power operating instructions, voids the warranty.

The front panel power switch is also
a circuit breaker. As a circuit breaker,
it prevents excessive current from
entering the PIU.
When the power is on, the switch is
illuminated. When the breaker trips,
the switch returns to its “off”
position.
Circuit Protection
Bryston PIUs will shut-down if
internal unit temperature reaches
excessive levels.
Thermal Protection
Per UL, CSA and National Electrical
codes, devices with line cords and
plugs must not consume more than
80% of a branch circuit’s rating.
While Bryston Power Isolation Units
are designed to handle well beyond
these limits, they must be marked
with a maximum input current that
satisfies the requirements.

recommended. Balanced input
products, 240VAC, require dual
120V phases (2 pole, 3-wire). Wall
outlets for 240VAC are rated at 250V
and will likely require special
installation. Dedicated outlets, or
any household or facility wiring
should be installed by a licenced
electrician to local codes.
Pictured below are suggested
receptacle types for installation.
